Answer the following statement(s) true (T) or false (F)
1. Although the light-emitting diode (LED) can be found in nearly every electronic circuit, it is not easy to spot unless you’ve had some training in electronics. 2. In a seven-segment LED display, which is used in calculators, automobile instrument panels, and countless other applications, each segment is an LED. 3. In a common-anode seven-segment LED display, each LED must have its own current-limiting resistor to prevent the LED from burning out. 4. A Zener diode might look like a PN junction diode, but it behaves drastically different in a circuit. 5. If a varying reverse bias is applied to a varactor diode, the capacitance will stay the same.
